Null User Object@lemmy.worldto Technology@lemmy.world•Japan Just Switched on Asia’s First Osmotic Power Plant, Which Runs 24/7 on Nothing But Fresh Water and SeawaterEnglish23·15 days agoI think the article author is completely confused and doesn’t understand what’s happening. There are hints of what’s happening in this paragraph.
Fresh water—or treated wastewater—is placed on one side of a membrane. On the other side is seawater, made even saltier by concentrating leftover brine from a desalination process. The difference in saltiness pulls the fresh water across the membrane, increasing the pressure on the saltwater side. That pressure is then used to drive a turbine, generating electricity.
I don’t think any fresh water is being used. I think what’s actually happening is…
Very salty wastewater (from the desalinization plant) is placed on one side of a membrane. On the other side is seawater. The difference in saltiness pulls the wastewater across the membrane, increasing the pressure on the saltwater side (or maybe the other way around). That pressure is then used to drive a turbine, generating electricity. The waste then is just water that’s saltier than sea water, but less salty than what came from the desalinization plant.

Do you turn off your heat at sunset in the winter? Maybe you do, but most people don’t.Also, most people with an electric car and a garage to park it can just use a cheap Level 1 charger to trickle charge it whenever it’s in the garage and always have plenty of range for their commute and errands. This means all of those cars are charging. … at night while the owner sleeps.

No. Just the LLM industry and AI slop image and video generation industries. All of the legitimate uses of AI (drug discovery, finding solar panel improvements, self driving vehicles, etc) are all completely immune from this lawsuit, because they’re not dependent on stealing other people’s work.

Null User Object@lemmy.worldto Fediverse@lemmy.world•I totally missed the point when PeerTube got so goodEnglish142·2 months agoIt depends on what info you’re trying to find.
I was recently trying to figure out the name of a particular uncommon type of pipe fitting. I could describe what it looked like, but had no idea what it was called. I described it to chatgpt, which gave me a name, which I could then search for with a normal search engine to confirm that the name was correct. Sure enough, search results took me to plumbing supply companies selling it, with pictures that matched what I described.
But, asking it when a particular feature got added to a piece of software? There’s no additional information one would get from the answer to help them confirm that the answer is correct.
ETA: The above strategy has also failed me many times, though, where chatgpt gives me information that follow-up searches only confirmed that chatgpt hallucinated the answer. Just wanted to say that to reinforce that you have to assume it’s hallucinating until you get independent confirmation.
